3. Restore the accessories power supply on terminals
L7-L8 and make sure that the led does not turn on
again.
Too long pre-blinking When a start command is given, the
flashing light turns on immediately, but the
gate doesn’t.
It means that the setup cycle count down expired and the
control unit shows that service is required (chapter 11.2)
The display shows Err1 The writing Err1 appears on display when

It means that changed data could not be stored.
This kind of defect has no remedy.
Contact the technical support centre V2.
The display shows Err2 When a start command is given, the door
doesn’t open at all
It means that MOSFET test failed.
Contact the technical support centre V2.
The display shows Err3 When a start command is given, the door
doesn’t open at all
It means that the photocell test failed.
1. Be sure that no obstacle interrupted the photocell
beam when the Start command was given.
2. Be sure that photocells, as enabled by their relevant
menus, have been installed actually.
3. Be sure that photocells are powered and working;
when you interrupt their beam, you should hear the
relay tripping.
The display shows Err5 When a start command is given, the door
doesn’t open at all
It means that the test of the safety edges failed.
Check that the menu of the test of safety edges (Co.tE)
have been set correctly.
Check that the safety edges enabled from the menu are
installed.
The display shows Err7 When a Start command is given and the
gate does not open (or does a partial
opening)
This indicates an error in the encoders’ operation.
Contact the technical support centre V2.
The display shows Err8 When executing a self-learning function,
the command is refused
It means that the setting of the control unit is not
compatible with the requested function.
In order to carry out self-learning, the Start inputs
must be enabled in standard mode (Strt menu set
to StAn) and the ADI interface must be disabled
(i.Adi menu set to no).
The display shows Err9 When you are trying to change the control
unit setups
It means that programming was locked by means of the
programming lock key CL1+ (code 161213).
